  2. 1. Boron compounds as additives to lubricants : synthesis, characterization and tribological optimization

    Author : Faiz Ullah Shah; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Developing new technological solutions, such as use of lightweight materials, less harmful fuels, controlled fuel combustion processes or more efficient exhaust gas after-treatment, are possible ways to reduce the environmental impact of machines. Both the reduction of wear and the friction control are key issues for decreasing of energy losses, improving efficiency and increasing of the life-span of an engine. READ MORE

  4. 2. Designed boron chemistry for tribological systems

    Author : Faiz Ullah Shah; Jean Michel Martin; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Boron compounds can be environmentally friendly alternatives for commercially available lubricant additives. Some boron compounds are already used as friction modifiers, corrosion inhibitors, antioxidants and antiwear additives in lubricants. READ MORE

  5. 3. Fluorine-Free Ionic Liquid Based Electrolytes: Synthesis and Structural Characterization

    Author : Mukhtiar Ahmed; Faiz Ullah Shah; Patrik Johansson; Jiayin Yuan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic Liquids; Electrolytes; Sustainability; Vitamin B3; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Since their introduction by Sony in 1990, lithium-ion batteries (LIBs) have acquired a sizable market share. They have the best energy densities, a high open circuit voltage, a low self-discharge rate, no memory effect, and a slow loss of charge when not in use. READ MORE

  7. 5. Active friction control by using CO2 and moisture

    Author : Jing Hua; Shi Yijun; Shah Faiz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction control; Machine Elements; Maskinelement;

    Abstract : Nowadays the demand for intelligent control of tribological interactions is strongly increasing in various applications. We often strive to minimize friction but there are also many situations where high friction is desirable. In some cases, something in between, i.e. READ MORE
